Multi-core Performance (30 ps). Designers are comparing performance between a many-core processor equipped with 32 in-order cores versus a quad-core superscalar processor. The quad-core superscalar processor has four identical Out-of-Order cores. Each core is a 2-issue superscalar. The many-core processor has 32 in-order processor cores. Each in-order core of the many-core processor can achieve about one tenth the performance of the OoO superscalar core. A benchmark program (bitcoin mining) includes both sequential codes that can only be executed on one CPU core and parallel codes that can be distributed to multiple CPU cores. For this program, execution of the sequential codes takes 20% of the total execution time. Please answer which processor would deliver faster performance for this application and show your calculations. Use a single in-order core performance as baseline.
